PALAEOZOIC FORAMINIFERA

RevueDeMicropaleontologie front.gif
...... the systematics, evolution and ecological behaviour of the first mineralized Palaeozoic Foraminifera are important to discuss in order to have a clearer picture of former shallow marine environments, and finally understand their distribution through space and time. The systematics of the fossil group of Foraminifera that first developed a mineralized test remains under discussion. These early foraminifers are considered as Textulariata (as generally admitted), recrystallized Fusulinata or an independent group, sometimes called Astrorhizata. In this paper, we argue to assign the early foraminifers to the Fusulinata, and to subdivide this class into six orders: Parathuramminida, Archaediscida and Earlandiida (forming together the subclass Afusulinana n. subcl.), and Tournayellida, Endothyrida and Fusulinida (subclass Fusulinana nom. translat.). These subdivisions are discussed and linked to the first occurrences of the later classes: Miliolata, Nodosariata and Textulariata.

MODERN FORAMINIFERAL DISTRIBUTION AND DIVERSITY IN ATOLLS

Marine Micropaleontology Front.gif
Foraminifera from the coral-reef lagoons of two atolls are used to investigate the distribution and diversity of assemblages in the central Indian Ocean. Eight assemblages and 270 species of foraminifera are identified. Three assemblages are reefal and dominated by Amphistegina and Calcarina. Only one lagoon assemblage is present in both atolls, which is characterized by abundant Ammonia sp. 1 and smaller miliolid foraminifera. ...... The assemblages compare well with sedimentological characteristics, which is also reflected in their distributions. Species diversity in the Maldives appears to be higher than the western Indian Ocean region due to the stronger influence of central Indo-Pacific faunas. It is not however, as high as the central Indo-Pacific region, which may be due to lower habitat diversity.

CENOZOIC TROPICAL PLANKTONIC FORAMINIFERAL BIOSTRATIGRAPHY

EarthScienceReview front.gif
...... In this paper we present an amended low-latitude (tropical and subtropical) Cenozoic planktonic foraminiferal zonation. We compile 187 revised calibrations of planktonic foraminiferal bioevents from multiple sources for the Cenozoic and have incorporated these recalibrations into a revised Cenozoic planktonic foraminiferal biochronology. We review and synthesize these calibrations to both the geomagnetic polarity time scale (GPTS) of the Cenozoic and astronomical time scale (ATS) of the Neogene and late Paleogene. ...... The revised and recalibrated datums provide a major advance in biochronologic resolution and a template for future progress of the Cenozoic time scale.

ENVIRONMENTAL CONTROLS ON A RIVER-DOMINATED SHELF

J Sea Research Front.gif
In this paper, we investigate the ecology of live (rose Bengal stained) benthic foraminifera collected at 20 stations ranging from 15 to 100 m depth in the Rhône prodelta (Gulf of Lions, NW Mediterranean). These sites were sampled in September 2006, five months after the Rhône River annual flood. Statistical analyses based on foraminiferal communities (N150 µm) divide our study area into six main biofacies directly related to environmental conditions. ...... We also compare foraminiferal faunas sampled in September 2006 with communities sampled in June 2005, one month after the Rhône River annual flood (Mojtahid et al., 2009). This comparison suggests that opportunistic species (e.g. B. aculeata, Cassidulina carinata, V. bradyana) have responded to organic matter inputs related to marine primary production in June 2005.

THE RATE OF 20TH CENTURY SEA LEVEL RISE

Quaternary Research front.gif
We collected a set of surface samples from two salt marshes in the Morbihan Golfe, France to determine foraminiferal distribution patterns ...... developed a foraminifera-based transfer function using a modern training set of 36 samples and 23 species. ...... The agreement between the foraminifera-based sea level curve and the Brest tide-gauge record confirms the reliability of transfer function estimates and the validity of this methodology to extend sea level reconstructions back into the pre-instrumental period. Both instrumental and microfossil records suggest an acceleration of sea level rise during the 20th century.

WHAT HAPPENS WHEN THE OCEAN IS OVERHEATED?

GAS Bulletin.jpg
The global warming and major perturbation of the global carbon cycle that occurred during the Paleocene–Eocene Thermal Maximum (PETM) have been investigated in the lower bathyal–upper abyssal Alamedilla section (Spain). Geochemical anomalies and dramatic faunal changes (including the globally recognized extinction event of deep-sea benthic foraminifera and the rapid evolutionary turnover of planktic foraminifera and calcareous nannofossils) are associated with the PETM at Alamedilla....Significant changes in foraminiferal test size are documented across the PETM.

TIMOR TRIASSIC AGGLUTINATED FORAMINIFERA

JFR cover.gif
Forty-nine species of organic-cemented siliceous agglutinated foraminifera are described from 11 different facies associations representing basinal deposits of the Triassic in Timor Leste. The facies associations containing the foraminifera range from those influenced by sediment derived from nearby carbonate banks to prodelta and delta-front associations. A survey of equivalent faunas from selected shallow-marine basins ranging from the Carboniferous to the mid-Cretaceous illustrates the conservative development through time of the siliceous agglutinated foraminifera.

LIVE FAUNAS ALONG A BATHYMETRICAL TRANSECT

RevueDeMicropaleontologie front.gif
In a 10-stations bathymetrical transect in the Bay of Biscay, we observed important changes in the density, composition and microhabitats of live foraminiferal faunas from the outer continental shelf to the abyssal plain.....The foraminiferal data together with the pore water data in the sediment give evidence of the presence of a trophic gradient from very eutrophic settings at the upper continental shelf towards oligotrophic settings at the abyssal area.

FORAMINIFERAL RESPONSES TO ABSENCE OF FRESH PHYTODETRITUS

Marine Micropaleontology Front.gif
The study illustrates that the quality of organic material has an important impact on the composition and maintenance of some benthic foraminiferal communities, that the faunal response to reduction, or even a halt, in the supply of fresh phytodetritus, is not necessarily immediate or dramatic, and that the response depends on the trophic conditions prevailing in the area when the halt occurs.

ONTOGENETIC EFFECTS ON δ¹³C and δ18O

Marine Micropaleontology Front.gif
We determined the stable oxygen and carbon isotopic composition of live (Rose Bengal stained) tests belonging to different size classes of two benthic foraminiferal species from the Pakistan continental margin. Our data underline the necessity to base longer δ18O and δ13C isotope records derived from benthic foraminifera on size windows of 100 μm or less. This is already common practice in down-core isotopic studies of planktonic foraminifera.

FORAMINIFERA IN SOIL

Soilforams.jpg
Environmental SSU rDNA-based surveys show that Foraminifera are a widespread and diverse component of soil microbial communities. Phylogenetic analysis clusters them in four groups branching among the radiation of early foraminiferal lineages. Identification of terrestrial foraminiferal species and understanding of their ecological role represent an exciting challenge for future research.

JURASSIC VENT FORAMINIFERA

App-cov.jpg
Recurvoides infernus sp. nov., one of the oldest representatives of the superfamily Recurvoidacea (Foraminifera), is described from a black claystone overlying the manganese deposits in the Western Tatra Mountains (Poland). These manganese carbonates/silicates were laid down around a shallow−water exhalative submarine hydrothermal vent that was active in the early Toarcian. The microfossils are possibly the first described Jurassic foraminifera associated with hydrothermal vents (from ABSTRACT).

DECADAL-SCALE CHANGES IN ABYSSAL FORAMINIFERAL ASSEMBLAGES

Deep-Sea Research II front.gif
Trends in the abundance, diversity and taxonomic composition of ‘live’ (rose Bengal stained) foraminiferal assemblages (0-1 cm layer, >63-µm fraction) were analysed in replicate multiple corer samples collected at the Porcupine Abyssal Plain (48˚ 50’ N, 16˚ 30’ W, 4850 m water depth) over a 13-yr period (1989-2002). Overall, the abyssal time-series revealed decadal-scale changes among shallow-infaunal foraminifera, more or less coincident with changes in the megafauna, as well as indications of shorter-term events related to seasonally-pulsed phytodetrital inputs.

DAN-C2 HYPERTHERMAL EVENT AT GUBBIO

EarthPlanetarySciLetters front.gif
TThe Dan-C2 event is an early Danian, transient (∼100 kyr) hyperthermal episode centered at ∼65.2 Ma, which records shifts in carbon reservoirs and ocean warming in the northwestern and southeastern sectors of the Atlantic Ocean. Here we present and discuss high-resolution biochronostratigraphic and magnetic susceptibility data and geochemical records from the western Tethyan Contessa Highway section (Gubbio, Italy), which provide the first direct evidence of the Dan-C2 event beyond the Atlantic Ocean and point to the supra-regional, possibly global, significance thereof.

ECOLOGICAL AND EVOLUTIONARY RESPONSE TO MECO

PPP front.gif
The enigmatic middle Eocene climatic optimum (MECO) is a transient (∼500kyr) warming event that significantly interrupted at ∼40 Ma the long-term cooling through the middle and late Eocene, eventually resulting in establishment of permanent Antarctic ice-sheet. ...... Here we present a detailed planktonic foraminiferal analysis of the MECO interval from a marginal basin of the central-western Tethys (Alano section, northeastern Italy). ...... High-resolution quantitative analysis performed on both >38 μm and >63 μm fractions reveals pronounced and complex changes in planktonic foraminiferal assemblages indicating a strong environmental perturbation that parallels the variations of the stable isotope curves corresponding to the MECO and post-MECO intervals.

SURVIVAL OF BENTHIC FORAMINIFERAL PROPAGULES

J Sea Research Front.gif
New data support our previously published propagule dispersal hypothesis and show that propagules of some benthic foraminiferal species can survive for two years before growth commences. Our results indicate substantial inter-specific differences in dispersal potential and support previous suggestions that among free-living species, some serial forms have the potential for long-distance dispersal.
